What is Lisrel and why do you need it?




Lisrel is an acronym for linear structural relations, which is the name of the software program and the method of SEM that it implements. SEM is a statistical technique that allows you to test and estimate complex relationships between observed and latent variables. Observed variables are those that you can measure directly, such as test scores, income, or satisfaction. Latent variables are those that you cannot measure directly, but that represent underlying constructs, such as intelligence, motivation, or quality.


Lisrel is a software program for structural equation modeling (SEM)




Lisrel was developed by Karl Jöreskog in 1970 as one of the first software programs for SEM. Since then, it has been updated and improved several times, with the latest version being Lisrel 10.20. Lisrel is a proprietary software package that requires a license to use. It is available for Windows operating systems only.


SEM is a powerful and flexible method for analyzing complex data




SEM is a method that combines factor analysis and regression analysis in one framework. It allows you to test hypotheses about the causal relationships between variables, as well as to measure the reliability and validity of your measurements. SEM can handle various types of data, such as continuous, categorical, ordinal, or count data. It can also deal with missing data, non-normality, measurement error, multicollinearity, moderation, mediation, multigroup comparisons, longitudinal data, multilevel data, and more.


Lisrel offers various features and benefits for SEM users




Lisrel has many features and benefits that make it attractive for SEM users. Some of them are:


  • It has a graphical interface that allows you to draw your SEM models using diagrams.



  • It has a syntax mode that allows you to write your SEM models using equations.



  • It supports various methods of estimation, such as maximum likelihood (ML), generalized least squares (GLS), weighted least squares (WLS), diagonally weighted least squares (DWLS), asymptotically distribution-free (ADF), Bayesian estimation (BAYES ), and robust maximum likelihood (RML).



  • It provides various fit indices and statistics to evaluate the goodness-of-fit of your SEM models, such as chi-square, root mean square error of approximation (RMSEA), comparative fit index (CFI), Tucker-Lewis index (TLI), standardized root mean square residual (SRMR), Akaike information criterion (AIC), Bayesian information criterion (BIC), and more.



  • It allows you to test various hypotheses and constraints on your SEM models, such as equality, inequality, linear, nonlinear, or quadratic constraints.



  • It produces various output files and tables that summarize the results of your SEM models, such as parameter estimates, standard errors, confidence intervals, p-values, residuals, modification indices, standardized solutions, indirect effects, total effects, and more.



  • It can generate various plots and graphs that illustrate the results of your SEM models, such as path diagrams, scatter plots, histograms, box plots, normal probability plots, residual plots, and more.
